As its name suggests, GraphOS is a platform for building and managing graphs . Each graph corresponds to a GraphQL service in your organization. Apollo Federation encourages a design principle called separation of concerns . This enables different teams to work on different products and features within a single graph, without interfering with each other. Limitations of type-based separation A supergraph enables the use of powerful tooling for schema management, metrics aggregation, and change validation. Learn more about GraphOS tooling. This auto-update flow will cause issues if you don't update your router version prior to updating your composition pipeline. We strongly recommend always specifying an exact federation_version . Preventing auto-updates
If it’s GraphQL federation implementation time, Tyk can help. You get started by creating subgraphs and supergraphs. With batched operation s, it's important to consider how an entire batch might impact rate limit calculations and query cost analysis to ensure that clients can't cheat rate limits through race conditions. The ELv2-licensed supergraph plugin (built from this source ) is installed to ~/.rover/bin if you installed with the curl | sh installer, and to ./node_modules/.bin/ if you installed with npm. Setting a composition version There are other benefits too, like an extension facility that lets you replace custom gateway code with configuration (this should sound familiar!) and comprehensive support for OpenTelemetry.The essential ideas of the supergraph are going to be pretty familiar to those who’ve been following Apollo for a while. It comes down to three core principles. 1: a unified composition layer Schmidt said the hope is that, at the end of the day, this abstraction can contribute to “making the world a little more human-centric.” This is because GraphQL can enable less rigid apps that conform to unique user tastes. But a robust composition layer will be necessary to allow such reconfigurations. need to explicitly specify them (otherwise, it would be something like cargo run — -s ./supergraph.graphql -c ./router.yaml. The supergraph works harmoniously with rapidly changing products because it empowers developers to ship schema changes swiftly and safely to support their own initiatives, causing the schema to naturally evolve based on actual usage and the needs of the business. On to the supergraph So when should you use either one? Many will say that federation is the overall winner, as it allows teams to focus on their application without needing to maintain a gateway. But if you have different types of APIs, you have to go with schema stitching.
Self-hosted supergraphs are an Enterprise feature for organizations with advanced performance or compliance requirements. If the command fails, make sure you've authenticated Rover with GraphOS . All Rover commands that interact with GraphOS require a valid API key. If your organization doesn't currently have an Enterprise plan, you can test out this functionality by signing up for a free Enterprise trial .A self-hosted supergraph is a supergraph with a router that you host and manage in your own infrastructure . This is in contrast to a cloud supergraph , which uses a router that's hosted and managed by Apollo. supports any existing Apollo Federation architecture (v1 or v2). Apollo Router as well as several other Apollo tools
Catches breaking changes at supergraph build time before a new supergraph is published, before they're published for Gateways to use. If you're new to GraphQL , we recommend starting your supergraph journey with the Lift-off tutorial series . GraphQL works by giving clients precisely the data that they request. Nothing more, nothing less. This means you can wave goodbye to the problems of over- and under-fetching. It does this through the use of schemas, which specify the types of objects that clients can request when they query the service. Developers define the object types in the schema, along with fields and resolvers (functions). Documentation for all your supergraph's types and fields. Supports filtering definitions by name, subgraph, and other values. Learn more If you're getting started with federation, we recommend creating a cloud supergraph with Apollo GraphOS . With a cloud supergraph , GraphOS provisions and manages your router for you!
Supports GraphQL federation natively
In a typical monolith scenario, you would have a single application that would give you all the needed information about the different missions and crew members. Instead, what you would want is one service to manage information about missions and another service to manage information about astronauts. In this case, you could easily split your monolith into two GraphQL instances. However, now, your frontend would no longer work because it would need to call two different APIs then stitch the information together.
